police dog

A police dog, also known as a K-9 (phonemic abbreviation of "canine"), is a dog that is trained to assist police and other law enforcement officers. Their duties may include searching for drugs and explosives, locating missing people, finding crime scene evidence, protecting officers and other people, and attacking suspects who flee from officers. The breeds most commonly used by law enforcement are the German Shepherd, Belgian Malinois, Bloodhound, Dutch Shepherd, and Labrador Retriever. In recent years, the Belgian Malinois has become the leading choice for police and military work due to their intense drive, focus, agility, and smaller size, though German Shepherds remain the breed most associated with law enforcement.
Police dogs are used on a national and local level for law enforcement purposes in many parts of the world. They are often assigned to what in some nations is referred to as a K-9 unit, with a specific handler, and must remember several verbal cues and hand gestures. Initial training for a police dog typically takes between eight months and a year, depending on where and how they are trained, and for what purpose. Police dogs often regularly take training programs with their assigned handler to reinforce their training. In many countries, intentionally injuring or killing a police dog is a criminal offense.
